Bob Carver 180 Mono-blocks perform superbly
The best amps I have heard are tubes, and use some feedback. True there are many feedback designs un-listenable, just as many zero feedback designs have their own set of issues, and to my ears lack musical believability. Jallen

Pass 250.5 shuts down driving Magnepan 3.7
At high volume, my 4BSST would flash red driving the 3.6. They suck power and need to be fed. Try a 14bsst, a bit more power will help, or get a bigger Pass. Jallen 
Psvane Teflon capacitors real or fakes?
I am afraid some distributors have been deceived about this product, along with consumers. I would like to hear about what Grant Fidelity and Parts Connexion have to say on this matter at this point. Both have great reputations to protect. I wonde... 
Psvane Teflon capacitors real or fakes?
Greetings,I received the test measurements from my friend and he stated similar findings. The 0.1 600V Psvane caps were measured using method F.T.I.R. Fourier Transformer Infrared Spectroscopy, and the material was determined to be polyester (ethy... 
Upgrade/recap of NAD 1300 worth trouble?
Only fix if broken. heating up the3 parts to desolder them only damages other parts, then more problems are created. They are all created connected, so solder and the trace heat other parts up, changing the values, and possibly delaminating the tr... 
Are Mcintosh Tube Amps really all that?
They measure good, sound good, and have been reliable for years, building both ss and tubes...how many other companies are accomplished historically as mac?Jallen 
Speaker suggestions at around $30k
I would get the legacy whisper with hurricane amps, and the updates by vh audio using v_caps. Stock the whisper when amped right is world class and will do rock to classical with a huge panel like stage but with dynamics and good slam. Upgraded, a... 
long speaker cables or IC's for budget system
For long interconnects use shielded ones, like microphone cables...mogami, canare, etc. Long speaker cables can increase the capacitance depending on design, not a great thing for some amps or the top end. jallen 
Tube question for the electrical engineers

who makes the best kt88 tube
There different versions "best" with regard to tubes. The most reliable could be the old genalec as many still work after years of use. Part of this is due to a well made tube, the other is their common use in mac circuits known for an easy tube l... 
Magnepan 3.6, 3.7 or Tannoy Westminister SE
I have had the 3.6 for many years and if fed properly, they are splendid....pass, bryston, parasound, some high power tube amps, etc. A Tannoy is a very different sound. The maggie treble is legendary and only bested by what I hear from TAD and pl... 
Best audio purchase of 2011
Ionovac plasma tweeters. Have to be heard....jallen 
Lifespan of a quality solid state amplifier?
Many new electrolytic caps are + or - 10-20% and they are usually further out of spec after 10-15 years. They may still work, but they are cheap, why not just replace them. I like Spragues or F&T. If they will fit, I use v-Caps in coupling or ...
